Well im getting a new short block put in. I think i had a broken wristpin and i scored # 1 cyl. so they say im gettin a new short block put in. Anything i need to do special to break it in? Im assuming it will be a factory rebuild and not a brand new one but i could be wrong. Will the dealer know if its new or rebuilt? Anyway i hope its on its way, i need to get back to work !!
